The Associated Press reports the death toll is expected to rise. Medical officials told wire services that at least 60 people have been hospitalised. When the storm ceased, the survivors emerged to see their city turned into a wasteland.

A child caught in the school has told KFor TV: "I had to hold on to the wall to keep myself safe...to not fly away" during the tornado.

Block after block of the community lay in ruins, with heaps of debris piled up where homes used to be. Cars and trucks were left crumpled on the roadside.

The National Weather Service issued an initial finding that the tornado was an EF-4 on the enhanced Fujita scale, the second most-powerful type of twister.

In video of the storm, the dark funnel cloud could be seen marching slowly across the green landscape. As it churned through the community, the twister scattered shards of wood, pieces of insulation, awnings, shingles and glass all over the streets.

Volunteers and first responders raced to search the debris for survivors.
